Jimmy Fallon on Monday — the eve of the 2024 presidential election — mocked former president and current GOP nominee Donald Trump over that weird rally moment with a microphone.

Trump in Wisconsin last week whined about the mic being too low. He then proceeded to bob his head up and down in what commentators suggested mimicked oral sex.

Fallon ran the tape of Trump on “The Tonight Show” and then cracked, “His staff was like, ‘Oh my God, he’s blowing it.’”

“Literally, he’s…” Fallon continued, before show announcer Steve Higgins chimed in, “Oh, come on. That sucks.”
